The movie is called The Boy in the Striped Pajamas.

It's about when some guy named Hitler, whoever that is. Starting bring Jewish people to a concentration camp. ((An: I KNOW WHO THIS IS, CALY, BEING TRAPPED ON AN ISLAND FOR 3000 YEARS DOES NOT K?))
I did my research on this.

Watch the movie, I swear you wont regret it, it's on Netflix.

My opinion: IT'S SOOOOO SAD.

The dad is some type of soldier who got a promotion.

His wife disagrees with his treatment of Jews. ((These are not spoilers))

Their is a sister who is supporting her father.

And our main character who befriends a Jew who is trapped in the camp.

* WARNING * IT IS SUPER SAD. I was crying my eyes out in the end.

If your too lazy or just don't want to watch it, Pm me and I'll explain it all, or Wikipedia it.
